Slow WAN ODBC Connect - Beating a Dead Dog
My ODBC pauses 10 seconds between queries. I have read some of the other threads on this subject but nothing has helped. Maybe if someone sees my details I can find a solution:
Redhat Linux 2.4.20-8
MySQL 4.1.10 or 4.1.10a (I have one of each server on two machines)
MyODBC 3.51.3, 3.51.10, 3.51.11-3
Everything was fine while I was using 3.51.10 and 4.0 but when I upgraded to 4.1 it slowed way down. The LAN is fine no pausing.
This is a report of the tethereal sniff (Look at the 10 seconds intervals, they should be concurrent then a few are concurrent and then intervaled, again):
